1JZ / 2JZ - Oil Level Sensor Block Off AN10 Breather
More than a block off. A better breather solution.
 
This 1JZ 2JZ oil level sensor block off plate is yet another addition to our JZ platform lineup. Beyond simply blocking off the factory sensor, this plate doubles as a dedicated crank case breather.
 
Crafted to perfection using CAD design, the plate is machined from aerospace 6061 aluminum with T6 heat treatment, ensuring extreme durability even in the most demanding conditions.
 
With this AN10 breather plate, you can remove the old oil level sensor and connect an AN10 hose directly into your PCV system, helping further reduce crank case pressure for cleaner, more consistent engine performance.
 
This block off comes complete with a free AN10 fitting and 4x M6 stainless steel fasteners, so it's ready to install right out of the box.
